Title:
MOISTURE-PERMEABLE WATER-PROOF SHEET FOR BUILDING MATERIALS
Document Type and Number:
WIPO Patent Application WO/2010/092877
Kind Code:
A1
Abstract:
Disclosed is a moisture-permeable water-proof sheet for building materials, which is light-weight, can keep an excellent peg hole-sealing properties even after the sheet is exposed to severe environmental conditions, can protect from the ingress of water, and has excellent moisture-permeability. Specifically disclosed is a moisture-permeable water-proof sheet (1) for building materials, which is characterized by comprising a non-woven fabric layer (2) which has a bulk density of 0.01 g/cm3 or more, a porous polyolefin film layer (3) which is laminated on the upper surface of the non-woven fabric layer (2) and has water-proof properties and moisture-permeability, and an air-permeable adhesive resin layer (4) which is produced by adhering the non-woven fabric layer (2) and the porous polyolefin film layer (3) and in which multiple linear resins (11) are arranged almost parallel to one another in a planar view, wherein the width of each of the linear resins in the air-permeable adhesive resin layer (4) is 0.5 to 3 mm and the width of a gap formed between the adjacent linear resins is 0.1 to 1 mm.
